Kho Jian, a metalworker from Louhe in Henan province, central China, is designing and building the craft using re-salvaged and converted oil tanks.
The 'Noah's Ark' will come at a cost of £20,000, and will be fitted with a range of mod-cons including a kitchen and bathrooms.
It will also use technology that is employed for space travel in order to keep it watertight - while also providing doors and windows.
'He believes we are heading for a world flood and he wants his own ark to save himself and his family,' said Kho, who aims to have the finished craft ready for delivery soon.

Sun Chao, a crafstman from Kaiyuan, China, spent 4 months working on this project. The result is a fully-functional bicycle made from over 10,000 Popsicle sticks. Its inaugural ride lasted 20 minutes and easily supported his 200lb weight.
